Filed `uly 10, 1961, Ser. No. 123,401 3 Claims. (Ci. Zitti-56) The invention concerns cont-ainers and more particularly a refillable discharge container of soft products for replaceable use in vending machine dispensing soft product.

`An object of the invention is to provide a new, improved, more economical and more hygienic means for replenishing soft product in vending machine when empty with more soft product.

A feature of the invention is an improved discharge container of soft products having a new resiliently balanced transverse member with a new functionally actuating sealing parts mechanism and with essential new characteristics to provide a special fitness for a new series of function and use particularly to ensure itful coaction of steps and sequences of operation with the discharge mechanism of a vending machine, especially:

(l) To substantially increase the frictional resilient sealing tightness capable to withstand all applied pressure without leakage by the discharge, and by the refilling also to ensure denseness without space cleavage for the purpose of the discharge of an exact great predetermined purchased quantity of soft product by limited space displacement of a slidably nested, resiliently balanced transverse member in a casing by checking pressure motion of a vending machine by the means of a functionally actuating sealing parts mechanism of said transverse member effectively increasing sealing tightness by the backpressure of the soft product filling against two associated contiguous equilibrate sealing parts projections, forcing them further apart in order to rise the resilient frictional sealing pressure of the sealing parts projections by the generated backpressure of the soft product thereon.

(2) To provide a casing with a new resiliently balanced transverse member in order to resist at all time attack to break the seal by radially expanding two annular projections permanently united With said transverse member and to facilitate rised sealing friction of the adjoining parts of said transverse member and casing without upsetting and jamming by the means of the two associated contiguous equilibrate sealing parts projections engaging said transverse member with the inner periphery of said casing during their passage from one peripheral stop end to the other peripheral stop end, and providing therewith a doubled seal with a reduced area of friction surface for the movable closure of said two resilient projections with rised sealing tightness due to substantially greater diameter of said transverse member as the inside diameter of said casing.

(3) And finally to provide said container with essential new characteristics to comply with fitful coaction of steps and sequences of operation with a novel series of function and use in a vending machine to resist successfully wear and fracture, to facilitate maintenance and acquire suitable properties to be appropriately filled, discharged, replaced and refilled by securing said resiliently balanced transverse member in said casing by opposite peripheral stop ends with the provision to be operably, reciprocably and permanently retained in said casing from which can be separable only by breakage.

Other objects and fuller understanding of the invention may be had by referring to the following description and claims, taken with the accompanying drawing, in which:

FIGURE l is a perspective view of a container according to the invention with partial sections at the con- ,e ICC tainer ends showing features respectively therein and thereon.

FIGURE 2 is an enlarged cross-sectional View of a transverse member mounted in said casing, and

FIGURE 3 is an enlarged cross-sectional view of both ends of said container with said transverse member at one end and a removable cover on the other end.

The discharge container comprises a casing 1 having two opposite open ends 3, 4, provided with peripheral stop ends, for coupling and locking two annular projections 15, 16 of a transverse member 2 and enveloping it with the inside wall 17, one of said stop end of lthe filled casing having a resiliently expandable gripping socket 9 to clutch in seal engagement a resiliently contractual bolt projection 16 of said resiliently balanced transverse member 2 and close said casing on said one open end 3; and the opposite stop end having a trapping socket or inwardly open channel 12, to engage a springy wedge-rim projection 15, concavo diverging from the free side 14 of said bolt 16, to stop and permanently retain said transverse member in said casing on the opposite stop end 12; and the opposite open end of the filled casing 4 is provided with a removable cover 5 to close said container when it is stored and not in use in a vending machine.

In the casing, the casing end 3 is peripherally crimped to form an axially extending projection 6 having a radial fiange '7 extending inwardly with respect to the casing 1. The projection 6 has outwardly curved shoulders 8 that are oppositely disposed and define a resiliently expandable gripping socket 9 extending both axially and radially to a flared interior opening 10. The opposite casing end 4 of the casing 1 is turned radially inward and axially back to form an axially extending flange 11 and define an inwardly opening channel or trapping socket 12 between the overlapping portions of the casing end 4.

The transverse member 2, shown in FIGURE 2, is roughly bowl-shaped with a flat bottom 13 and is resiliently balanced by the associated assistance of two contiguous equilibrate sealing parts projections comprising a resiliently contractual bolt projection 16, extending therefrom to concavo-jut sides 14 with axially diverging springy wedge-rim projection 15 to resiliently stabilize it in a casing 1. The adjoining periphery of the bottom 13 and sides 14 are peripherally arrow-shaped where they join to form an inwardly open resiliently contractual bolt projection 16 extending both radially and axially outward and shaped complementary to the gripping socket 9 defined by the casing end 3 for clutch seal engagement therein when the casing is filled and for later frictional resilient sealing engagement with the inner periphery of the casing 1, when disengaged therefrom.

The removable cover 5 is cup shaped with a flat bottom 18 and peripheral sides 19 normal thereto. The cover fits over the casing end 4 when the filled casing is not used and the sides 19 engage the casing 1 to retain the cover thereon.

In a full discharge container the casing 1 is closed at casing end 3 by the transverse member 2 engaging its resilient bolt projections 16 in the complementary shaped resiliently expandable gripping socket 9 and together by its outwardly flared concavo diverging springy wedge-rim projection 15 being forced into resilient frictional sealing contact with the inner periphery 17 of the casing 1, the said resilient frictional sealing contact of which being further substantially increased proportionally to the degree of the backpressure of the soft product against two associated contiguous equilibrate sealing parts projections 15, 16, forcing them further apart in order to rise the resilient frictional sealing pressure of said sealing parts projections against the inner periphery of said casing and so more effectively increasing their sealing tightness in a manner in which the applied discharge and refilling pressure on the soft product with tendency to break the seal proportionally establishes the sealing tightness of the functionally actuating sealing parts projections 15, 16, by the generated backpressure of the soft product thereon. After removing the cover 5 from casing end 4, and inserting said container with the open end down into a vending machine, from the discharge mechanism generated pressure on the bottom 13 of the transverse member 2 in the direction of the casing end 4 disengages the bolt projection 16 from the gripping socket 9 and slides the transverse member 2 longitudinally toward casing end 4,

discharging the soft product therefrom. The functionally actuating sealing parts mechanism is actuated by the backpressure of the soft product on the transverse member two contiguous equilibrate sealing parts projections 15, 16, in order to force them further apart and so increasing more effectively the sealing contact with the inner periphery of the casing 1, the sealing pressure varying proportionally with the backpressure of the soft product in a manner in which the pressure power developed from squeezing said soft product with tendency to break said seal is overpowered by the backpressure against said two equilibrate sealing parts projections 15, 16 to always ensure a sealing contact for all applied pressure. The upper outer resiliently contractual bolt projection 16 when disengaged from the resiliently expandable gripping socket 9 comes into peripheral resilient sealing contact with the inner periphery 17 of the casing 1 and being axially spaced from the free wedge-rim projection in similar resilient contiguous equilibrate sealing contact, the transverse member 2 is so assisted in resilient balance in ord'er to facilitate sliding friction and is prevented from upsetting and jamming in its travel toward casing end 4, and when the transverse member 2 approaches the casing end 4, its free wedge-rim projection 15 engage in the trappingI socket or stop channel 12 to prevent the transverse member 2 from being forced out of the casing 1, and the discharge container is ready for removing and refilling without the dispense of all of the material which will hold because the resiliently balanced transverse member 13 is on the casing end 4 permanently retained and cannot be pressed out. The discharge container is refilled by forcing soft product into the casing end 4, the transverse member 2 traveling back to the casing end 3 where the complementary shaped resilient inwardly open contractual bolt projection 16 is clutched by the gripping socket 9 and so prevented from being forced out of the casing 1 and the bottom 13 reengaging therewith the radial flange 7 of the casing end 3.

The resiliently balanced transverse member 2 is by said stop ends 9, 12 reciprocably, operably and permanently nested in said casing 1 which can be separable only by breakage for the purpose to provide new essential characteristics for new functions and use to comply with litful coaction of steps and sequences for a reusable operation in a vending machine to resist successfully wear and fracture, to facilitate maintenance and to acquire suitable properties to be appropriately filled, discharged, refilled and replaced in a vending machine, and with the resilient arrangement of the contiguous equilibrate sealing parts projections 15, 16, the transverse member 2 is assisted in harmonious balance and is provided with a substantially greater diameter on the projections ends 15, 16 as the inside diameter of said casing 17 in order to double therewith the seal with a rised sealing tightness and to facilitate sliding friction without upsetting and jamming by the reduced area of friction with the friction points 15, 16 movable closure in casing inner side 17, and whereby said sealing parts projections 15, 16 are by the discharge and refilling forced by the backpressure further apart in order to substantially increase the sealing tightness by the generated backpressure of the soft product thereon.

Although the invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
